For what it’s worth - vanilla JS is pretty darn good and if you’re only dipping in for some small functionality I highly doubt a framework brings much benefit.
I find vanilla JS unusable for anything bigger, though. It was designed for quickie scripts on throwaway web pages, but it's not great for anything you'd call a web app.
Typescript, however, does scale pretty well. But now you've added a compiler and bundler, and might as well use some framework.
